The invention discloses a steel pipe truss concrete laminated slab which comprises a reinforced concrete bottom plate and a steel pipe truss, a plurality of longitudinal prestressed steel bars are distributed in the reinforced concrete bottom plate, and the steel pipe truss comprises a steel pipe and wavy steel bars welded to the two sides of the steel pipe. The wave-shaped reinforcing steel bar comprises a wave crest section, a wave trough section and a web member between the wave crest section and the wave trough section, and the wave trough of the wave-shaped reinforcing steel bar is embedded into the reinforced concrete bottom plate. The web members are welded to the steel pipes, the welding portions are arranged at or near the tangent points where the wavy steel bars intersect with the steel pipes, the horizontal height of the welding portions is 0.5-3 cm away from the wave crests, the vertical included angles of the web members are inwards reduced to be 2 degrees, and the vertical included angles of the web members are outwards expanded to be not larger than 5 degrees. And the overall structural stability of the steel pipe truss prestressed concrete laminated slab is better.
本发明公开了一种钢管桁架混凝土叠合板，包括钢筋混凝土底板、钢管桁架，所述钢筋混凝土底板内布设有多根纵向预应力钢筋，所述钢管桁架包括钢管和焊接在钢管两侧的波浪形钢筋，所述的波浪形钢筋包括波峰段、波谷段和波峰段与波谷段之间的腹杆，所述的波浪形钢筋的波谷嵌入到钢筋混凝土底板内，其特征在于所述波浪形钢筋的波峰两侧有与钢管焊接的焊接部位，且焊接部位设置在波浪形钢筋与钢管相交的切点或切点附近，所述焊接部位的水平高度距波峰0.5‑3cm，腹杆竖向夹角内缩小于2度，腹杆竖向夹角外展不大于5度，具有提高叠合板内部支承结构的强度，使钢管桁架预应力混凝土叠合板整体的结构稳定性更好。
